Alzheimer’s disease symptoms include a progressive loss of recent memory... and disorientation to time and place.

Lewy body dementia (LBD) is an umbrella term for a form of dementia that has three common presentations.

• Some individuals will start out with a memory or cognitive disorder that may resemble Alzheimer’s disease.

• Others will start out with a movement disorder leading to the diagnosis of Parkinson's disease and later develop dementia and other symptoms common in DLB (‘dementia with Lewy bodies’).

• Lastly, a small group will first present with neuropsychiatric symptoms, which can include hallucinations, behavioral problems, and difficulty with complex mental activities, leading to an initial diagnosis of DLB.
